Sorry, improper word usage. What I meant was that after I created the AACS folder in the Program Data folder, pasted
keydb.cfg - Language English (17444 entries in there and then decompressed it, there was a two folders in AACS with the same name keydb.cfg: The one I decompressed and the one that-somehow?-appeared and that was compressed.
I did open the decompressed folder. Windows calls it a config fig and it's 45,426KB. But I don't see anything in it, which is not surprising because it's a file not a folder. However,
when I opened that decompressed file (folder) the compressed folder disappeared. Then when I clicked Explorer's Back arrow the compressed folder reappeared.
I would suggest duplicating these steps and decide if you want to decompress the other keydb.cfg folder.
